FIG. 1 is a view illustrating an example of an external appearance of a camera module according to an embodiment of the present disclosure.

FIG. 2 is a view illustrating an example of an exploded perspective view of another camera module according to an embodiment of the present disclosure.

Referring to FIGS. 1 and 2, the camera module 100 according to the embodiment of the present disclosure may include a shield can 110, a stopper 120, a variable aperture 130, an aperture fixing unit 140, a first movable carrier 150, a lens barrel 160, a second movable carrier 180, an aperture driving module 170, and a housing 190. In the above-described camera module 100, the variable aperture 130 may is disposed on the lens barrel 160, and the size of an aperture hole area 130 a of the variable aperture 130 may be adjusted by the aperture driving module 170. For example, the camera module 100 may change an adjustment state of the variable aperture 130 according to a photographing function (or a photographing mode). For example, the camera module 100 may be adjusted such that the size of the aperture hole area 130 a may be maximized when a first photographing function (e.g., a pan-focusing function) is executed. The camera module 100 may be adjusted such that the size of the aperture hole area 130 a may be minimized when a second photographing function (e.g., an out focus function) is executed.

According to various embodiments, the camera module 100 may be adjusted such that the size of the aperture hole area 130 a of the variable aperture 130 may correspond to a specific size area between a maximum value and a minimum value. The above-described camera module 100 according to the present disclosure may have a state in which the variable aperture 130 is disposed together with the first movable carrier 150, to which the lens barrel 160 is coupled, while being disposed on the lens barrel 160. Accordingly, the camera module 100 may include the variable aperture 130 that may be moved in the X-axis, Y-axis, or Z-axis direction in correspondence to the movement of the lens barrel 160. The camera module 100 with the above-described structure may minimize the height of the camera module 100 by minimizing a gap between an uppermost end of the lens barrel 160 and the aperture hole area 130 a of the variable aperture 130 while the variable aperture 130 is disposed on the lens barrel 160.

The shield can 110 may cover the camera module 100 from the upper side to the lower side as a whole. For example, the shield can 110 may include an upper surface 111, and shield can side walls 112 disposed at a periphery of the upper surface 111, and a lower surface of the shield can 110 may be opened. The upper surface 111 of the shield can 110 may have a shield can hole 110 a of a specific size such that at least a portion of the lens 161 disposed at a central portion of the lens barrel 160 may be exposed. The shield can side walls 112 may be coupled to a periphery of the housing 190 of the camera module 100 to function to fix the configurations (e.g., the stopper 120, the variable aperture 130, the aperture fixing unit 140, the first movable carrier 150, the lens barrel 160, the second movable carrier 180, and the aperture driving module 170) seated in the interior of the shield can 190. The shield can 110, for example, may be formed of a metallic material or may be formed of a material (e.g., reinforced plastics) having a hardness of a specific value or more.

The stopper 120 may be disposed between the shield can 110 and the variable aperture 130 to prevent the variable aperture 130 from deviating in one direction (e.g., the Z-axis direction or the upward direction). In this regard, the stopper 120 may include an upper substrate 125 and leads 124. The upper substrate 125 may include a peripheral area 121 having a polygonal band (e.g., a rectangular band) shape, a central portion of which is empty, and a stopper substrate 122 including a stopper hole 120 a that is provided at a central portion thereof to have a specific size such that the aperture hole area 130 a of the variable aperture 130 may be exposed. The stopper substrate 122 may be connected and fixed to one side of the peripheral area 121 through a connecting portion 123. Further, the stopper substrate 122 may be disposed on an upper side, which is spaced apart from the peripheral area 121 by a specific height (e.g., the height of the connecting portion 123) through the connecting portion 123. The stopper substrate 122 is spaced apart from the variable aperture 130 by a specific interval due to the height of the connecting portion 123 to allow upward and downward movements of the variable aperture 130. The leads 124 may be formed on sides (e.g., corner areas) of the peripheral area 121 to have a vertical length and a width. According to an embodiment, the leads 124 may have a band shape, a central portion of which is empty. The leads 124 may be coupled to one side of the first movable carrier 150 or the second movable carrier 180.

The variable aperture 130 may include two wing parts 130_1 and 130_2. The wing parts 130_1 and 130_2 may partially overlap each other. The overlapping wing parts 130_1 and 130_2 may be fixed to be rotated in a specific angle range. Each of the wing parts 130_1 and 130_2 may include wing holes 131 a and 131 b having different sizes and portions of which overlap each other, at a central portion thereof. The wing holes 131 a and 131 b partially overlap each other to form the central aperture hole area 130 a. The wing holes 131 a and 131 b may have a shape in which at least portions of holes having different sizes overlap each other, for example, a roly poly or a snowman. According to various embodiments, the wing holes 131 a and 131 b may include a plurality of holes that are spaced apart from each other by a specific interval.

The wing parts 130_1 and 130_2 may be engaged with each other to be moved in a direction in which they become far away from each other or closer to each other in a specific angle range. For example, when the wing parts 130_1 and 130_2 are moved in a direction in which they become closer to each other (or a direction in which an overlapping range of the wing parts 130_1 and 130_2 becomes larger), the aperture hole area 130 a may increase, and when the wing parts 130_1 and 130_2 are moved in a direction in which they becomes far away from each other (or a direction in which an overlapping range of the wing parts 130_1 and 130_2 becomes smaller), the aperture hole area 130 a may decrease. The above-described wing parts 130_1 and 130_2 are seated on one side of the first movable carrier 150, and may be rotated in specific angle ranges, respectively.

The aperture fixing unit 140 may be provided such that a periphery of one side of the variable aperture 130 is fixed to the first movable carrier 150 and the variable aperture 130 may be rotated in a specific range. For example, the aperture fixing unit 140 may be provided such that a lever 139 used to rotate the variable aperture 130 in a specific range may be moved in a specific range while a wing holder 132 disposed on one side of the wing part of the variable aperture 130 is fixed to the first movable carrier 150 (e.g., fixed to prevent upward and downward movement of the wing part holder 132). In this regard, the aperture fixing unit 140 may include a cover 141 disposed to cover an upper surface of a corner area of the variable aperture 130 to prevent deviation of the variable aperture 130 in the Z-axis direction, and a side lead 142 disposed to overlap a side of the corner area of the variable aperture 130 to move the lever 139 at a specific angle while preventing deviation of the variable aperture 130 in the X-axis direction or Y-axis direction (or a specific direction on a horizontal plane).

The first movable carrier 150 is provided such that an inner central portion is empty and an upper side of the lens barrel 160 is disposed in the inner central portion, the variable aperture 130 is seated on and fixed to an upper side of the first movable carrier 150, and the first movable carrier 150 may be coupled to the variable aperture 130 such that the wing parts 130_1 and 130_2 of the variable aperture 130 may be rotated in a specific angle range. The lens barrel 160 may be fixed to an inside of the first movable carrier 150, and a first magnet member 151 and a second magnet member 152 (e g , hand-shaking compensating magnet members) disposed on at least two outer sides of the first movable carrier 150 may be disposed. The at least two outer sides may include sides that share corners. The first magnet member 151 and the second magnet member 152 for compensating hand-shaking may form pairs with hand-shaking compensation related coils (e.g., coils 191 and 192 disposed on one side of the housing 190) disposed in the second movable carrier 180 such that the first movable carrier 150, to which the lens barrel 160 is fixed, may be moved in the X-axis or Y-axis direction.

The lens barrel 160 has a tub shape, the interior of which is empty, and has the same or similar diameter from the bottom to a specific height thereof, the diameter of the lens barrel 160 gradually decreases as it goes from the specific height to an upper side, and the lens hole 161a is disposed at an upper end of the lens barrel 160. One or more lenses are disposed in the interior of the lens barrel 160 to be spaced vertically apart from each other by a specific interval. At least a portion of the uppermost lens 161 of the lenses disposed in the interior of the lens barrel 160 may be exposed to the outside through the lens hole 161a. According to an embodiment, the lens 161 may have a convex shape, and may protrude further to the upper side than to a periphery of the lens hole 161 a. A fixing recess or a fixing boss 162, by which the first movable carrier 150 is fixed, may be disposed on one side of the lens barrel 160. The lens barrel 160 fixed to the first movable carrier 150 may be moved in the X-axis and Y-axis directions (e.g., a specific direction on the horizontal plane) due to an interaction between the first magnet member 151 and the second magnet member 152 disposed in the first movable carrier 150 and the coils (e.g., the first coil 191 and the second coil 192) disposed on one side of the housing 190.

A through-hole 180 a of a specific size or more may be provided at a central portion of the second movable carrier 180, and the second movable carrier 180 may include a frame 189 that forms the through-hole 180 a, and one or more carrier side walls 181, 182, 183, and 184 extending from a periphery of the frame 189 to the upper side. For example, the carrier side walls 181, 182, 183, and 184 may include a first carrier side wall 181 formed such that the first magnet member 151 for moving the lens barrel 160 in the X-axis direction is exposed, a second carrier side wall 182 formed such that the second magnet member 152 for moving the lens barrel 160 in the Y-axis direction is exposed, a third carrier side wall 183 formed such that the third magnet member 188 for moving the lens barrel 160 in the Z-axis direction is disposed on the outside, and a fourth side wall 184 in which an aperture driving module 170 related to adjustment of the wing parts 130_1 and 130_2 of the variable aperture 130 is disposed. The lens barrel 160, to which the first movable carrier 150 is coupled, may be seated inside the above-described second movable carrier 180.

The aperture driving module 170, for example, may include a support 174 disposed on one side of the variable aperture 130, coupled to the lever 139 configured to deliver a force to move the variable aperture 130 in a specific angle range, and configured to move the lever 139 in a specific direction (e.g., in one direction on the horizontal plane, for example, the X-axis direction), a fourth magnet member 173 disposed in the support 174, an aperture coil 172 configured to move the fourth magnet member 173 in a specific direction (e.g., the X-axis direction), and an aperture driving IC 171 configured to control supply of electric power to the aperture coil 172. The aperture driving IC 171 and the aperture coil 172, for example, may be fixed to one side of the housing 190. Further, the support 174, in which the fourth magnet member 173 is disposed, may be attached and fixed to one side (e.g., the fourth carrier side wall 184) of the second movable carrier 180.

A seating part 198, in which the above-described configurations, for example, the stopper 120, the variable aperture 130, the aperture fixing unit 140, the first movable carrier 150, the lens barrel 160, the second movable carrier 180, and the seating part 198 in which the aperture driving module 170 are seated, and housing side walls 90 surrounding the above-described configurations may be disposed in the housing 190. The seating part 198 may include a seating part hole 190 a, through which a central portion of the lens barrel 160 is exposed downwards, at a central portion thereof An image sensor, for example, may be disposed under the seating part hole 190a.

The housing side walls 90 may be disposed at peripheries of the seating part 198 while sharing the corners. The housing side walls 90, for example, may include a first housing side wall 91 in which the first coil 191 mutually operated with the first magnet member 151 disposed in the first movable carrier 150 is disposed such that the lens barrel 160 may be moved in the X-axis direction, a second housing side wall 92 in which the second coil 192 mutually operated with the second magnet member 152 disposed in the first movable carrier 150 is disposed such that the lens barrel 160 may be moved in the Y-axis direction, a third housing side wall 93 in which the third coil 193 mutually operated with the third magnet member 188 disposed in the first movable carrier 150 is disposed such that the lens barrel 160 may be moved in the Z-axis direction, and a fourth housing wall 94 in which the aperture coil 172 mutually operated with the fourth magnet member 173 is disposed. The housing side walls 90 may protect the configurations related to the above-described camera module while being coupled to the shield can side walls 112.

The above-described camera module 100 according to the present disclosure may have a structure in which the variable aperture 130 also may be moved as the lens barrel 160 is moved, by employing a structure in which the variable aperture 130 is fixed to the lens barrel 160 while the variable aperture 130 is disposed on the lens barrel 160. Accordingly, the arrangement state of the lens barrel 160 and the variable aperture 130 may be maintained regardless of movement of the lens barrel 160 (e.g., movement related to compensation of hand shaking or movement related to auto-focusing). Further, the camera module 100 according to the present disclosure may minimize the vertical thickness of the camera module 100 by aligning the aperture hole area 130 a of the variable aperture 130 with the uppermost lens 161 disposed inside the lens barrel 160 and exposing at least a portion of the uppermost lens 161 having a convex shape through the aperture hole area 130 a (e.g., making an end of the convex surface of the uppermost lens 161 protrude further than a surface of the variable aperture 130).

According to various embodiments, the variable aperture 130 may be seated on the aperture holder 64.

As described above, the variable aperture 130 may include a first wing part 130_1 and a second wing part 130_2. The first wing part 130_1, for example, may include a first wing 134 a, a first wing support 133 a connected to the first wing 134 a, a first wing holder 132 a connected to the first wing support 133 a, a lever 139, and a connection boss 135 a. The second wing part 130_2, for example, may include a second wing 134 b, a second wing support 133 b connected to the second wing 134 b, a second wing holder 132 b connected to the second wing support 133 b, and a connection hole 135 b.

The first wing 134 a, for example, may have various shapes, for example, a polygonal shape while having a specific thickness. A first upper hole 137 a 2 and a first lower hole 137 a 1 may be disposed on one side of the first wing 134 a, and the first upper hole 137 a 2 and the first lower hole 137 a 1 may partially overlap each other. The diameter of the first upper hole 137 a 2 and the diameter of the first lower hole 137 a 1 may be different. According to an embodiment, the diameter of the first upper hole 137 a 2 may be smaller than the diameter of the first lower hole 137 a 1. Accordingly, the first upper hole 137 a 2 and the first lower hole 137 a 1 may have a roly poly shape, a snowman shape, or a figure eight shape. According to various embodiments, the first lower hole 137 a 1 and the first upper hole 137 a 2 may be spaced apart from the first wing 134 a by a specific interval. For example, the first lower hole 137 a 1 may be a circular hole of a first size, the second upper hole 137 a 2 may be a circular hole of a second size (e.g., which is the same as or smaller than the first size), and the first lower hole 137 a 1 and the first upper hole 137 a 2 may be spaced apart from each other. Similarly, the second lower hole 137 b 1 and the second upper hole 137 b 2 may be independent circular holes. In this case, the first lower hole 137 a 1 and the second lower hole 137 b 1 may overlap each other while the wing parts 130_1 and 130_2 are rotated to maximally overlap each other, and the first upper hole 137 a 2 and the second upper hole 137 b 2 may overlap each other while the wing parts 130_1 and 130_2 are rotated to minimally overlap each other.

As the wing parts 130_1 and 130_2 are moved, the first upper hole 137 a 2 may be disposed on the center point of the lens hole 161 a. Then, the first upper hole 137 a 2 may be disposed on the lens hole 161 a while overlapping the second upper hole 137 b 2 provided in the second wing 134 b. As the wing parts 130_1 and 130_2 are moved, the first lower hole 137 a 1 may be disposed on the center point of the lens hole 161 a. Then, the first lower hole 137 a 1 may be disposed on the lens hole 161 a while overlapping the second lower hole 137 b 1 provided in the second wing 134 b.

The first wing support 133 a may extend from a periphery of one side of the first wing 134 a while having a specific angle (e.g., a vertical angle) with a surface of the first wing 134 a. The first wing support 133 a has a cylindrical shape having a specific thickness and a specific width, and may be convex toward the lens barrel 160. A lower side of the above-described wing support 133 a may be held on the aperture holder 64. As the height of the first wing support 133 a, for example, is larger than the height of the upper barrel 63, the first wing 134 a may be spaced apart from the front surface of the upper barrel 63 at a designated interval.

The first wing holder 132 a is connected to a lower side of the first wing support 133 a and may extend from the center of the lens barrel 160 outwards while having a specific area. Accordingly, for example, the first wing part 130_1 may function to prevent the variable aperture 130 from deviating in the Z-axis direction while being at least partially covered by the stopper 120. The first wing holder 132 a may be disposed on one side of an upper portion of the first movable carrier 150.

The lever 139 may protrude from one side of the first wing holder 132 a in a specific direction. The lever 139 may move in a specific direction (e.g., forwards and rearwards in the X-axis direction) through driving of the aperture driving module 170 while being coupled to the aperture driving module 170. The lever 139 may transmit a force that moves the first wing holder 132 a while moving in one direction through driving of the aperture driving module 170, and the first wing 134 a connected to the first wing support 133 a may be rotated in a specific angle range while the force due to the movement of the first wing holder 132 a is transmitted to the first wing support 133 a. The first upper hole 137 a 2, the first lower hole 137 a 1, or the area in which the first upper hole 137 a 2 and the first lower hole 137 a 1 overlap each other may be positioned on the lens hole 161 a in correspondence to the rotation of the first wing 134 a.

The connection boss 135 a may be disposed on one side of the first wing 134 a, and may be disposed in a specific area in which the first wing 134 a overlaps the second wing 134 b. According to an embodiment, the connection boss 135 a may protrude toward a rear surface of the first wing 134 a, and may be inserted into the connection hole 135 b provided on one side of the second wing 134 b. The connection boss 135 a may move in the connection hole 135 b along the shape of the connection hole 135 b. Accordingly, a rotational force is transmitted to the connection boss 135 a while the first wing 134 a is rotated in a specific angle range, and the second wing 134 b including the connection hole 135 b may be rotated in a specific angle range in correspondence to the movement of the connection boss 135 a.

The second wing 134 b may have a shape that is substantially the same as or similar to that of the first wing 134 a, except for the connection hole 135 b. For example, the second wing 134 b may include a second upper hole 137 b 2 and a second lower hole 137 b 1. The second upper hole 137 b 2 and the second lower hole 137 b 1 may at least partially overlap each other, and the second upper hole 137 b 2 may have a diameter that is larger than that of the second lower hole 137 b 1. The second upper hole 137 b 2 may be disposed on the lens hole 161 a to at least partially overlap the first upper hole 137 a 2 as the second wing 134 b is rotated Similarly, the second lower hole 137 b 1 may be disposed on the lens hole 161 a to at least partially overlap the first lower hole 137 a 1 as the second wing 134 b is rotated.

The second wing support 133 b is disposed on one side of the second wing 134 b, and may extend perpendicularly to a surface of the second wing 134 b while having a specific thickness and a specific width. The second wing holder 132 b may be connected to a lower side of the second wing support 133 b. A lower side of the second wing support 133 b may be seated on an upper surface of the aperture holder 64 of the lens barrel 160, and may move along the upper surface of the aperture holder 64 in a specific angle range. The second wing support 133 b has a shape that is similar to or the same as that of the first wing support 133 a, and may be disposed to be symmetrical to the first wing support 133 a with respect to the lens hole 161 a.

The second wing holder 132 b may be disposed under the second wing support 133 b to have a specific area. The second wing holder 132 b may prevent the variable aperture 130 from deviating in the Z-axis direction while being covered by one side of the stopper 120. The second wing holder 132b may have a shape that is substantially similar to or the same as that of the first wing holder 132 a, except for an area of the lever 139. The second wing holder 132 b may be seated on an upper surface of the first movable carrier 150.

The connection hole 135 b may be provided on one side of the second wing 134 b while having a specific length. The connection boss 135 a provided in the first wing 134 a may be inserted into the connection hole 135 b. The connection boss 135 a seated in the connection hole 135 b may be moved along an inner peripheral surface of the connection hole 135 b by a specific distance. The connection hole 135 b may have a curved shape. Accordingly, while the first wing 134 a is rotated in a specific angle range, the second wing 134 b may be rotated at a specific angle while the connection boss 135 a is moved along the curved inner peripheral surface of the connection hole 135 b.

The size of the overlapping area of the first wing part 130_1 and the second wing part 130_2, which have been described above, may vary in correspondence to control of the aperture driving module 170 coupled to the lever 139. According to an embodiment, the first wing part 130_1 and the second wing part 130_2 may overlap each other maximally while the first lower hole 137 a 1 of the first wing part 130_1 and the second lower hole 137 b 1 of the second wing part 130_2 overlap each other on the lens hole 161 a. As a periphery of the first wing 134 a contacts a boss formed in the second wing support 133 b while the first lower hole 137 a 1 and the second lower hole 137 b 1 overlap each other, the first wing 134 a and the second wing 134 b may be fixed not to moved further in a specific direction. Further, the first wing part 130_1 and the second wing part 130_2 may overlap each other minimally while the first upper hole 137 a 2 of the first wing part 130_1 and the second upper hole 137 b 2 of the second wing part 130_2 overlap each other on the lens hole 161 a. Then, a minimum overlapping area of the first wing 134 a and the second wing 134 b may be fixed according to a coupling state of the connection hole 135 b and the connection boss 135 a.

The first movable carrier 150 may be fixedly coupled to the middle barrel 62 of the lens barrel 160, the aperture holder 64 and the upper barrel 63 are exposed to the upper side, and the lower barrel 61 may be exposed to the lower side. Sides of the wing holders of the variable aperture 130 may be seated on the first movable carrier 150. According to an embodiment, the first wing holder 132 a of the first wing 134 a may be seated on one side of the first movable carrier 150, and the aperture fixing unit 140 may be disposed on the upper side of the first movable carrier 150 while covering the first wing holder 132 a. Then, the lever 139 extending from the first wing holder 132 a may protrude in one direction through a recess provided in the aperture fixing unit 140.

FIG. 6A is a view illustrating a first state of a camera module according to a change of a variable aperture according to an embodiment of the present disclosure.

FIG. 6B is a view illustrating a second state of a camera module according to a change of a variable aperture according to an embodiment of the present disclosure.

Referring to FIGS. 6A and 6B, the camera module 100 according to an embodiment of the present disclosure, the shield can 110 having a shield can hole 110 a of a specific size at a central portion thereof surrounds the outside of the camera module 100 and the above-mentioned housing 190 may be disposed in the interior of the shield can 110. The lens barrel 160, to which the first movable carrier 150 and the second movable carrier 180 are coupled, may be seated in the housing 190, and the stopper 120, a central portion of which protrudes to the outside through the shield can hole 110 a may be disposed in the interior of the shield can 110. The peripheral area 121 and the leads 124 of the upper substrate 125 of the stopper 120 may be disposed under the shield can 110, and the stopper substrate 122 and the connecting portions 123 of the upper substrate 125 may be exposed to the outside through the shield can hole 110 a. The stopper hole 120 a may be arranged on the lens hole 161 a of the lens barrel 160 such that the lens hole 161 a may be exposed to the upper side. The size of the stopper hole 120 a, for example, may be the same as or larger than the size of the lens hole 161 a. Further, according to design, the stopper hole 120 a may have a size that is smaller than the size of the lens hole 161 a.

The aperture driving module 170 may be disposed on one side of the housing 190. An area of a side of the shield can 110 may be removed such that at least a portion (e.g., the aperture coil 172 or the aperture driving IC 171) of the aperture driving module 170 disposed on one side of the housing 190 may be exposed to the outside. The aperture coil 172 or the aperture driving IC 171 exposed through the removed side of the shield can 110, for example, may be connected to a control unit of the electronic device, on which the camera module 100 is mounted. A current of a specific direction may be supplied to the aperture coil 172 under the control of the aperture driving IC 171. If electric current flows to the aperture coil 172 in a specific direction, the fourth magnet member 173 disposed in the support 174 may move the support 174 in a first direction. If electric current flows to the aperture coil 172 in another direction, the fourth magnet member 173 disposed in the support 174 may move the support 174 in a second direction. According to an embodiment, the support 174 may move forwards and rearwards with respect to a transverse direction on a side of the shield can 110. The lever 139 may be moved through forward and rearward movement of the support 174.

If the lever 139 is moved in one direction (e.g., a rightward direction with respect to a point at which the aperture coil 172 is disposed in the illustrated drawing) through the motion of the support 174, the first wing part 130_1 and the second wing part 130_2 may be moved in a direction in which the overlapping area increases as in a first state (e.g., state 601, a state in which the first lower hole 137 a 1 of the first wing 134 a and the second lower hole 137 b 1 of the second wing 134 b completely overlap each other) illustrated in FIG. 6A. Accordingly, the first lower hole 137 a 1 provided in the first wing 134 a and the second lower hole 137 b 1 provided in the second wing 134 b may be exposed through the upper side of the lens hole 161 a while overlapping each other.

If the lever 139 is moved in another direction (e.g., a leftward direction with respect to a point at which the aperture coil 172 is disposed in the illustrated drawing) through the motion of the support 174, the first wing part 130_1 and the second wing part 130_2 may be moved in a direction in which the overlapping area decreases as in a second state (e.g., state 602, a state in which the first upper hole 137 a 2 of the first wing 134 a and the second upper hole 137 b 2 of the second wing 134 b completely overlap each other) illustrated in FIG. 6B. Accordingly, the first upper hole 137 a 2 provided in the first wing 134 a and the second upper hole 137 b 2 provided in the second wing 134 b may be exposed through the upper side of the lens hole 161 a while overlapping each other.

As described above, the camera module 100 according to an embodiment of the present disclosure may adjust an area in which the lens hole 161 a of the upper surface of the lens barrel 160 is exposed, by using the variable aperture 130 disposed on the lens barrel 160. According to an embodiment, the variable aperture 130 may be in a state of FIG. 6A in a photographing function (e.g., a pan-focusing function) that requires a relatively large amount of light, and the variable aperture 130 may be in a state of FIG. 6B in a photographing function (e.g., an out-focus function) that requires a relatively small amount of light.

FIG. 7A is a view illustrating various examples of a first adjustment state of an aperture hole area of a variable aperture according to an embodiment of the present disclosure.

FIG. 7B is a view illustrating various examples of a second adjustment state of an aperture hole area of a variable aperture according to an embodiment of the present disclosure.

FIG. 7C is a view illustrating various examples of a third adjustment state of an aperture hole area of a variable aperture according to an embodiment of the present disclosure.

FIG. 7D is a view illustrating various examples of a fourth adjustment state of an aperture hole area of a variable aperture according to an embodiment of the present disclosure.

Referring to FIG. 7A, the camera module 100 according to an embodiment of the present disclosure, a first adjustment state 701 (e.g., a large aperture hole area) of the aperture hole area 130 a may be formed as the first lower hole 137 a 1 of the first wing 134 a and the second lower hole 137 b 1 of the second wing 134 b overlap each other. In this regard, the aperture driving module 170 may operate the lever 139 disposed in the first wing part 130_1 such that the first wing 134 a and the second wing 134 b may move from the outside to the inside of a longitudinal center line of the camera module 100 with respect to the longitudinal center line. While the above-described aperture hole area 130 a is in the first adjustment state 701, the lever 139 may be moved downwards with respect to the illustrated drawing and may be moved by a maximally movable distance. Additionally, the lever 139 may be stopped not to move further downwards, by the aperture fixing unit 140. According to various embodiments, the support 174 of the aperture driving module 170 for moving the lever 139 may be designed to limit a first direction maximum movement distance (e.g., a maximum movement distance for the first adjustment state 701).

Referring to FIG. 7B, the camera module 100 according to an embodiment of the present disclosure may form a second adjustment state 702 of the aperture hole area 130 a (e.g., a star type aperture hole area) as a first size area of the first lower hole 137 a 1 of the first wing 134 a and the second lower hole 137 b 1 of the second wing 134 b, a second size area of the second upper hole 137 b 2, a third size area of the first upper hole 137 a 2 and the second lower hole 137 b 1 of second wing 134 b, and third size areas of the second upper hole 137 b 2 overlap each other. In this regard, the aperture driving module 170 may operate the lever 139 disposed in the first wing part 130_1 such that the first wing 134 a and the second wing 134 b may move from a longitudinal center line of the camera module 100 outwards by a first angle with respect to the longitudinal center line. The second adjustment state 702 of the above-described aperture hole area 130 a may be a state in which the lens hole 161 a is partially covered by the variable aperture 130. The second adjustment state 702, for example, may be a state that is undergone when the state is changed from the first adjustment state 701 to a fourth adjustment state 704 described in FIG. 7D. Further, as a specific photographing function is executed, the variable aperture 130 may be temporarily fixed in the second adjustment state 702.

Referring to FIG. 7C, the camera module 100 according to an embodiment of the present disclosure may form a third adjustment state 703 of the aperture hole area 130 a (e.g., a diamond type aperture hole area) as a fourth size area of the first lower hole 137 a 1 of the first wing 134 a and the second lower hole 137 b 1 of the second wing 134 b overlap each other, and a sixth size area of the first upper hole 137 a 2 of the first wing 134 a and the second lower hole 137 b 1 of the second wing 134 b and a seventh area of the second upper hole 137 b 2 overlap each other. In this regard, the aperture driving module 170 may operate the lever 139 disposed in the first wing part 130_1 such that the first wing 134 a and the second wing 134 b may move from a longitudinal center line of the camera module 100 outwards by a second angle (e.g., a specific angle that is larger than the first angle) with respect to the longitudinal center line. The third adjustment state 703 of the above-described aperture hole area 130 a may be a state in which the lens hole 161 a is covered by the variable aperture 130 more. The third adjustment state 703, for example, may be one of states that are undergone when the state is changed from the first adjustment state 701 to a fourth adjustment state 704 described in FIG. 7D. Further, as a specific photographing function is executed, the variable aperture 130 may be temporarily fixed in the second adjustment state 703.

Referring to FIG. 7D, the camera module 100 according to an embodiment of the present disclosure, a fourth adjustment state 704 (e.g., an aperture hole area having an elliptical shape or an egg shape) of the aperture hole area 130 a may be formed as the first upper hole 137 a 2 of the first wing 134 a and the second upper hole 137 b 2 of the second wing 134 b overlap each other. In this regard, the aperture driving module 170 may operate the lever 139 disposed in the first wing part 130_1 such that the first wing 134 a and the second wing 134 b may move from a longitudinal center line of the camera module 100 outwards by a third angle (a maximum angle that may be widened by a specific angle or outwards as compared with the second angle) with respect to the longitudinal center line. The fourth adjustment state 704 of the above-described aperture hole area 130 a may be a state in which the lens hole 161 a is covered by the variable aperture 130 more than in the third adjustment state. The fourth adjustment state 704 may be temporarily fixed as a specific photographing function is executed.

According to various embodiments, the above-described second adjustment state 702, for example, may be a state in which the support 174 for operating the lever 139 is moved from the first adjustment state 701 in a first direction by a second distance (e.g., 0.4 mm, which may vary according to the size of the camera module 100 or the like). The above-described third adjustment state 703, for example, may be a state in which the support 174 for operating the lever 139 is moved from the first adjustment state 701 in the first direction by a third distance (e.g., 0.6 mm, which may vary according to the size of the camera module 100 or the like). The above-described fourth adjustment state 704, for example, may be a state in which the support 174 for operating the lever 139 is moved from the first adjustment state 701 in the first direction by a fourth distance (e.g., 0.7 mm, which may vary according to the size of the camera module 100 or the like).

FIG. 8 is a view illustrating an example of a camera module related to movement of some configurations including a lens barrel according to an embodiment of the present disclosure.

Referring to FIG. 8, the camera module 100, for example, may include a second movable carrier 180 in which some configurations related to the lens barrel 160 are seated, and a third magnet member 188 and a third coil 193 (e.g., an auto-focusing related coil) configured to move the second movable carrier 180 including the lens barrel 160 in an upward/downward direction (or the Z-axis direction) and a focusing driving IC 197 may be included in the housing 190 in which the second movable carrier 180 is seated. For example, the third magnet member 188 may be fixed to one side of the second movable carrier 180, and the third coil 193 and the focusing driving IC 197 may be disposed on one side of the housing 190, at least a portion of which faces the third magnet member 188. Accordingly, if electric power is supplied to the third coil 193, the third magnet member 188 may interact with the third coil 193 to move the second movable carrier 180 upwards and downwards.

Additionally, a fourth magnet member 173 related to driving of the lever 139 of the variable aperture 130 may be disposed on one side of the second movable carrier 180 of the camera module 100, and the aperture coil 172 that interacts with the fourth magnet member 173, the aperture driving IC, and the like may be disposed in the housing 190 and the like. According to various embodiments, in the camera module 100, the first magnet member 151 and the second magnet member 152 may be disposed on one side of the first movable carrier 150 such that some configurations including the lens barrel 160 may be moved on a horizontal plane, and a first coil 191, a second coil 192, a driving IC related to driving of the first coil 191 and the second coil 192, and the like may be disposed in the housing 190.

FIG. 9A is a view illustrating a first state of a Z-axis movement of a camera module according to an embodiment of the present disclosure.

FIG. 9B is a view illustrating a second state of a Z-axis movement of a camera module according to an embodiment of the present disclosure.

Referring to FIG. 9A, in the camera module 100, some configurations (e.g., the second movable carrier 180) including the lens barrel 160 may be seated on the bottom of the housing 190. In a state in which the lens barrel 160 is seated in the housing 190, the variable aperture 130 positioned on the lens barrel 160 may be located below the upper surface of the shield can 110. Accordingly, the stopper 120 positioned on the upper side of the variable aperture 130 may be disposed at a height that is substantially similar to the height of the upper surface of the shield can 110. Further, at least a portion (e.g., a portion of a lower end of the lens barrel 160) of the lens barrel 160 may be located in the seating part hole 190 a disposed at the center of the bottom of the housing 190.

Referring to FIG. 9B, in the camera module 100, some configurations (e.g., the second movable carrier 180) including the lens barrel 160 may be located at a specific height from the bottom of the housing 190. In a state (or coming-over state) in which the lens barrel 160 is spaced apart from the bottom of the housing 190 by a specific height, the variable aperture 130 positioned on the lens barrel 160 may be disposed at a height (e.g., a state in which the variable aperture is parallel to the upper surface of the shield can 100) that is substantially similar to the upper surface of the shield can 110. Accordingly, the stopper 120 positioned on the variable aperture 130 is disposed at a height that is higher than the upper surface of the shield can 110 so that the stopper 120 protrudes further than the outer surface of the shield can 110 when viewed from the outside. Further, a lower end of the lens barrel 160 may be disposed at a height that is higher than the height of the seating part hole 190 a disposed at a central portion of the housing 190.

According to various embodiments, in relation to the performance of the auto-focusing function of the camera module 100, the lens barrel 160 may move toward the bottom of the housing 190 or in a direction in which the lens barrel 160 becomes far away from the bottom of the housing 190. According to various embodiments, if an auto-focusing function or a zoom-out function of the camera module 100 is executed, a control unit of the camera module 100 or the electronic device, on which the camera module 100 is mounted, may adjust a supply direction of electric current to the third coil 193 such that some configurations including the lens barrel 160 may become closer to or contact the bottom of the housing 190. According to various embodiments, if an auto-focusing function or a zoom-in function of the camera module 100 is executed, a control unit of the camera module 100 or the electronic device, on which the camera module 100 is mounted, may adjust a supply direction of electric current to the third coil 193 such that some configurations including the lens barrel 160 may be spaced apart from the bottom of the housing 190 by a specific height. Then, the direction of the current supplied to the third coil 193 may be different from a direction of the current supplied to the third coil 193 described in FIG. 9A.

FIG. 10 is a view illustrating an example of a hand shaking compensation related configuration of a camera module according to an embodiment of the present disclosure.

Referring to FIG. 10, the camera module 100 may include a first coil 191 disposed to prevent hand-shaking of some configurations including the lens barrel 160 in the X-axis direction, and a second coil 192 disposed to prevent hand-shaking of some configurations including the lens barrel 160 in the Y-axis direction. The first coil 191 and the second coil 192 may be disposed on one side of the housing 190, and may be disposed on an inner wall that may face an outer wall of the first movable carrier 150. The first magnet member 151 may be disposed in an area of one side of the first movable carrier 150, which faces the first coil 191. The second magnet member 152 may be disposed in an area of one side of the first movable carrier 150, which faces the second coil 192.

The electronic device 1300 may include a printed circuit board, in which the processor 1320, the memory 1330, and the sensor 1350 are seated, and a case for protecting the printed circuit board and the display 1370. A hole may be formed on one side of the case such that the camera module 1360 may be disposed in the hole. Accordingly, one surface (e.g., a surface on which a lens hole is disposed) of the camera module 1360 may be exposed to the outside through the hole formed on one side of the case. A cover (e.g., a glass cover) related to protection of the camera module 1360 may be disposed in the hole formed in the case.

According to an embodiment of the present disclosure, the processor 1320 may deliver a control signal related to driving of the camera module 1360 to the camera module 1360, and may output an image captured by the camera module 1360 through the display 1370 or store the image in the memory 1330. According to an embodiment, the processor 1320 may output a user interface (UI) related to selection of a photographing function using the camera module 1360 through the display 1370. For example, the processor 1320 may output a menu screen or an icon including a pan-focusing function selection item and an out-focus function selection item on the display 1370. The processor 1320 may deliver a first control signal corresponding to selection of the pan-focusing function or a second control signal corresponding to selection of the out-focus function to the camera module 1360.

According to various embodiments, the processor 1320 may deliver a control signal related to the first adjustment state 710 or a second control signal related to the fourth adjustment state 704 to the camera module 1360 based on sensor information collected by the sensor 1350. For example, the processor 1320 may identify whether the intensity of illumination of the outside is a specific illumination intensity or lower, based on the illumination intensity information provided by the sensor 1350. When the intensity of illumination of the outside is the specific illumination intensity or lower, the processor 1320 may deliver the first control signal to the camera module 1360. Further, when the intensity of illumination of the outside exceeds the specific illumination intensity, the processor 1320 may deliver the second control signal to the camera module 1360.

According to an embodiment, the input/output interface 1340 may include an audio device, and may output audio information corresponding to a current adjustment state of the variable aperture 130 of the camera module 1360. For example, if an input signal related to a request of activation of the camera module 1360 is generated, the audio device may output audio information corresponding to a current adjustment state of the camera module 1360. Further, if the adjustment state of the camera module 1360 is changed, the audio device may output audio information corresponding to the changed adjustment state.

The sensor 1350 may include at least one sensor related to management of the electronic device 1300. For example, the sensor 1350 may include an illumination sensor that may measure the intensity of illumination of the outside.

Although it has been exemplified in the illustrated description that the sensor 1350 is connected to the processor 1320, the present disclosure is not limited thereto. For example, the sensor 1350 may be directly connected to the camera module 1360. In this case, an image sensor IC included in the camera module 1360 may change management of the sensor 1350 and the adjustment state according to the management of the sensor 1350 (e.g., change the state of the variable aperture 130 to the first adjustment state 701 or change the variable aperture 130 to the second adjustment state 702 in correspondence to the illumination intensity information).

FIG. 14 is a view illustrating an example of a method for managing an electronic device including a camera module according to an embodiment of the present disclosure.

Referring to FIG. 14, in relation to the method for managing an electronic device according to an embodiment of the present disclosure, in operation 1401, the processor 1320 may activate a camera module. For example, the processor 1320 may provide an icon or a menu related to activation of the camera module or may provide a button related to activation of the camera module. If an input signal corresponding to an icon, the selection of a menu, or a button input is received, the processor 1320 may activate the camera module 1360 by supplying the camera module 1360 (e.g., the camera module 100) with electric power. Further, the processor 1320 may automatically activate the camera module 1360 if a request for execution of a function (e.g., manufacturing of a video) related to the camera module 1360 is made.

In operation 1430, the processor 1320 may identify a setting function. For example, the processor 1320 may identify whether an input signal related to change of an adjustment state of the variable aperture 130 is generated. Further, the processor 1320 may identify an adjustment state value of the variable aperture 130, which has been set to a default value. Further, the processor 1320 may identify illumination intensity information of the outside.

When execution of the pan-focusing function (or a function set to maintain the variable aperture 130 in the first adjustment state 701) in operation 1403, the processor 1320 may adjust the state of the variable aperture 130 to a first state (e.g., a state in which the first lower hole 137 a 1 of the first wing 134 a and the second lower hole 137 b 1 of the second wing 134 overlap each other or the first adjustment state 701) in operation 1405.

When execution of the out-focusing function (or a function set to maintain the variable aperture 130 in the fourth adjustment state 704) in operation 1403, the processor 1320 may adjust the state of the variable aperture 130 to a second state (e.g., a state in which the first upper hole 137 a 2 of the first wing 134 a and the second upper hole 137 b 2 of the second wing 134 overlap each other or the fourth adjustment state 704) in operation 1407.

According to various embodiments, if deactivation of the camera module 1360 is requested, the processor 1320 may deactivate the camera module 1360 after maintaining the state of the variable aperture 130 in a specific state (e.g., the first state or the second state). For example, when a pan-focusing function of the management function of the camera module 1360 is mainly used, the processor 1320 may deactivate the camera module 1360 after the state of the variable aperture 130 is changed to a first state if the state of the camera module 1360 shortly before the deactivation of the camera module 1360 is a second state. Further, when an out-focusing function of the management function of the camera module 1360 is mainly used, the processor 1320 may deactivate the camera module 1360 after the state of the variable aperture 130 is changed to the second state if the state of the camera module 1360 shortly before the deactivation of the camera module 1360 is the first state.

According to various embodiments, if deactivation of the camera module 1360 is requested, the processor 1320 may deactivate the camera module 1360 after maintaining the state of the variable aperture 130 in a specific state (e.g., the first state or the second state) according to the intensity of illumination shortly before the request for deactivation. For example, when the intensity of illumination shortly before the deactivation of the camera module 1360 is a specific illumination intensity or lower, the processor 1320 may deactivate the camera module 1360 after the state of the variable aperture 130 is changed to the first state or maintained. Further, when the intensity of illumination shortly before the deactivation of the camera module 1360 exceeds a specific illumination intensity, the processor 1320 may deactivate the camera module 1360 after the state of the variable aperture 130 is changed to the second state or maintained.

According to various embodiments, when deactivation of the camera module 1360 is requested, the processor 1320 may restore the adjustment state of the variable aperture 130 with reference to the initial state of the aperture coil 172 and the third magnet member 188. For example, if the initial state of the aperture coil 172 and the third magnet member 188 is designed to be a first state (e.g., a state in which the lever 139 is moved such that the first lower hole 138a1 and the second lower hole 137b1 overlap each other) when the electronic device 1300 is designed, the processor 1320 may deactivate the camera module 1360 after the variable aperture 130 is restored to the first state when the camera module 1360 is deactivated. For example, if the initial state of the aperture coil 172 and the third magnet member 188 is designed to be a second state (e.g., a state in which the lever 139 is moved such that the first upper hole 137 a 2 and the second upper hole 137 b 2 overlap each other) when the electronic device 1300 is designed, the processor 1320 may deactivate the camera module 1360 after the variable aperture 130 is restored to the second state when the camera module 1360 is deactivated.

According to various embodiments, the method for managing an electronic device according to an embodiment may include an operation of receiving a request for deactivation of a camera, and a variable aperture adjusting operation of adjusting or maintaining the size of an aperture hole area of a variable aperture disposed on a lens barrel according to a specific condition.

According to various embodiments, the variable aperture adjusting operation may include an operation of identifying illumination intensity information, and an operation of adjusting the aperture hole area to a first size (or a maximum size) when the intensity of illumination is a specific value or higher.

According to various embodiments, the variable aperture adjusting operation may include an operation of identifying illumination intensity information, and an operation of adjusting the aperture hole area to a second size (e.g., a size that is smaller than the first size or a minimum size) when the intensity of illumination is a specific value or higher.

According to various embodiments, the variable aperture adjusting operation may include an operation of identifying a set photographing function, and an operation of adjusting the aperture hole area to a first size (or a maximum size) when the set photographing function is a pan-focusing function.

According to various embodiments, the variable aperture adjusting operation may include an operation of identifying a set photographing function, and an operation of adjusting the aperture hole area to a second size (e.g., a size that is smaller than the first size or a minimum size) when the set photographing function is an out-focusing function.

At least part of the kernel 1541, the middleware 1543, or the API 1545 may be referred to as an operating system (OS).

The kernel 1541 may control or manage, for example, system resources (e.g., the bus 1510, the processor 1520, or the memory 1530, and the like) used to execute an operation or function implemented in the other programs (e.g., the middleware 1543, the API 1545, or the application program 1547). Also, as the middleware 1543, the API 1545, or the application program 1547 accesses a separate component of the electronic device 1501, the kernel 1541 may provide an interface which may control or manage system resources.

The middleware 1543 may play a role as, for example, a go-between such that the API 1545 or the application program 1547 communicates with the kernel 1541 to communicate data.

For example, the middleware 1543 may assign priority which may use system resources (the bus 1510, the processor 1520, or the memory 1530, and the like) of the electronic device 1501 to at least one of the at least one application program 1547. For example, the middleware 1543 may perform scheduling or load balancing for the one or more work requests by processing the one or more work requests in order of the priority assigned to the at least one of the at least one application program 1547.

The API 1545 may be, for example, an interface in which the application program 1547 controls a function provided from the kernel 1541 or the middleware 1543. For example, the API 1545 may include at least one interface or function (e.g., a command) for file control, window control, image processing, or text control, and the like.

The input and output interface 1550 may play a role as, for example, an interface which may transmit a command or data input from a user or another external device to another component (or other components) of the electronic device 1501. Also, input and output interface 1550 may output an instruction or data received from another component (or other components) of the electronic device 1501 to the user or the other external device.

The display 1560 may include, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 1560 may display, for example, a variety of content (e.g., text, images, videos, icons, or symbols, and the like) to the user. The display 1560 may include a touch screen, and may receive, for example, touch, gesture, proximity, or a hovering input using an electronic pen or part of a body of the user.

The communication interface 1570 may establish communication between, for example, the electronic device 1501 and an external device (e.g., a first external electronic device 1502, a second external electronic device 1504, or a server 1506). For example, the communication interface 1570 may connect to a network 1562 through wireless communication or wired communication and may communicate with the external device (e.g., the second external electronic device 1504 or the server 1506).

The wireless communication may use, for example, at least one of long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), or global system for mobile communications (GSM), or the like. Also, the wireless communication may include, for example, local-area communication 1564. The local-area communication 1564 may include, for example, at least one of wireless-fidelity (Wi-Fi) communication, Bluetooth (BT) communication, near field communication (NFC), or global navigation satellite system (GNSS) communication, and the like.

A magnetic security transmission (MST) module may generate a pulse based on transmission data using an electromagnetic signal and may generate a magnetic field signal based on the pulse. The electronic device 1501 may output the magnetic field signal to a point of sales (POS) system. The POS system may restore the data by detecting the magnetic field signal using an MST reader and converting the detected magnetic field signal into an electric signal.

The GNSS may include, for example, at least one of a GPS, a Glonass, a Beidou navigation satellite system (hereinafter referred to as “Beidou”), or a Galileo (i.e., the European global satellite-based navigation system) according to an available area or a bandwidth, and the like. Hereinafter, the “GPS” used herein may be interchangeably with the “GNSS”. The wired communication may include at least one of, for example, universal serial bus (USB) communication, high definition multimedia interface (HDMI) communication, recommended standard 232 (RS-232) communication, or plain old telephone service (POTS) communication, or the like.
